VLC can not play The Iron Lady DVD-Video. I copied it successfully using K9Copy, but it won't load the movie properly. I got the same problem with The King's Speech DVD-Video. I used K9Copy to make a backup copy successfully, but it won't play the movie.

Hugo and The Adventures of Tin Tin DVD-Videos are giving me the same problems. I can use K9Copy to make backup copies, but they won't play in VLC.

What is going on here?

How do I solve this problem so that I can play these movies?

What other software packages should I consider so that I can play these specific DVD-Video movies on my computer?
